Leiostyla anglica
Leiostyla anglica
Leiostyla anglica is a terrestrial snail from the family of Lauriidae.
Features
The housing is 3.1 to 3.7 mm high and 1.7 to 2.1 mm wide ( thick). It is egg-shaped with a blunt apex. The 5-6 ½ turns are only slightly convex, the suture is not particularly pronounced. It is reddish - brown, the surface is matt and provided with very weak growth lines. The mouth is U-shaped with a rounded lower edge. The whitish aperture rim is thickened, in particular in the center of the often somewhat indented outer lip. Up to six lamellar -like teeth protrude into the mouth: a Angularzahn, mostly very clearly developed and connected to the outer lip, a Parietalzahn, a Columellarzahn and two Palatalzähne that run near the base in the last turn into it.
The soft body of the animal is light, almost translucent, with dark - gray head and antennae. The upper sensors are long, the lower sensor is very short, more like tubercles.
Geographical occurrence, habitat and behavior
The presence of the species extends from Algeria, Madeira, West Spain and Portugal, West France ( only one locality at Calais ) on the Channel Islands to England, Scotland and Ireland. Earlier evidence of the type from Bulgaria have proven to be errors.
The species prefers rather damp habitats in swamps and shady woods. In central and southern England the species is even considered as an indicator of original forest areas. She lives there in the leaf litter, under stones and in moss. The species seems to tolerate relatively high temperatures.
Little is known about the lifestyle of the hidden wildlife.
Threats and conservation
The populations of the species in central and southern England are threatened by logging of old forests in decline and strong. It is more commonly found in Cornwall, Wales, Northern England, Scotland and Ireland.
